Scott,

 

I too wrote a startup script for systemd.  Your script may be better than mine , but I’ll post it as another example.

 

# cat /usr/lib/systemd/system/listserv.service

[Unit]

Description=LISTSERV startup script

After=syslog.target network.target postfix.service

 

[Service]

ExecStart=/listserv/go bg

ExecReload=/listserv/go bg

ExecStop=/usr/bin/kill `/usr/bin/cat /listserv/spool/listserv.PID`

PIDFile=/listserv/spool/listserv.PID

Type=simple

RemainAfterExit=yes

User=listserv

Group=listserv

 

[Install]

WantedBy=multi-user.target

Howdy,

 

I tried dropping the L-Soft provided sysV script into /etc/init.d on my new RHEL7 listserv server, but found that stopping the service under systemd failed to kill all the  ./lsv processes like it used to on RHEL5, leaving two ./lsv zombies to get in the way of maintenance operations. In general, killing the main Listserv PID as recommended by L-Soft just doesn’t seem to kill Listserv anymore:

 

kill `cat $LSVHOME/spool/listserv.PID`

 

 

Since I couldn’t find a reliable method to kill listserv all the way from the PID, I tried using the lcmd  tool to issue a clean SHUTDOWN command to listserv. I couldn’t convince listserv that root was authorized to run commands without making root@hostname a quiet, hidden Admin. Eventually I was able to convince lcmd to shutdown listserv, but I’m not sure if this is the best way.

 

Since I was re-writing the init script, I figured I might as well learn systemd. I came up with the following systemd unit file, (which relies on root@hostname to be a Listserv admin):

 

[Unit]

Description=Listserv mailing lists by LSoft

After=network.target postfix.service

 

[Service]

PIDFile=/home/listserv/spool/listserv.PID

ExecStart=/home/listserv/go bg

ExecReload=/home/listserv/go bg

KillMode=process

Restart=on-failure

RestartSec=42s

ExecStop=/usr/local/bin/lcmd  SHUTDOWN

 

[Install]

WantedBy=multi-user.target

 

 

Anyone have a better, more reliable way to register Listserv under systemd?
